Abstract
|
|
|
|
Surgeons still have many different views on the clinical significances of the lumbosacral transitional vertebrae as one of the causes of chronic low back pain and a higher incidence of adjacent disc degeneration. Moreover, in rare case reports, compression of the exiting nerve root due to abnormal articulation between the hypertrophied transverse process and the sacral ala has been proposed as one of the reasons for the far-out lumbosacral stenosis. Anterior or posterior surgical decompression is recommended in the cases that are refractory to conservative treatment. We reviewed the related literatures and report on a case that suffered from the far-out stenosis due to lumbosacral transitional vertebra and this was successfully treated by decompression using the posterolateral approach.
